I'm using 3/4 " hose from the pump to the soaker hose, the bigger hose lessens the chance of ice blockage. If you can keep the pump close to the pond that would probably be best unless your using a much bigger pump, mine is 200ft from the cabin next to the pond, some day I'll put in a heavy electric line but for now an extension cord does the job, the pump only draws 80 watts.
It's mounted in a plastic container, the sides are cut out with furnace filter material over it to allow air flow to the pump, the thermostat is mounted to the left.
If I can answer any other questions feel free, the guy's on this forum have given me tons of help.
